Firmware dump for the Microsoft Surface Pro 3, logic board part X896569-001, described as unpassss, which most likely means the password lock has been removed. The ZIP is 7.45 MB and holds a .bin image for writing to the flash chip with an external programmer. Such dumps are used when a device is locked by a forgotten firmware password or the firmware is damaged. Read and save the original chip before writing, verify the image size matches the chip, and note that device-specific data may need restoring.
